Systems and methods for side-channel monitoring a local network are disclosed. The methods involve generating a program trace signal from at least one of power consumption, electromagnetic emission, or acoustic emanation of a control processor connected to the local network and operating a monitoring processor to detect a communication of a message on the local network; identify at least one purported control processor related to the communication; analyze the program trace signal of the at least one purported control processor relative to the communication; and at least one of an authenticate or verify one or more purported control processors of the at least one purported control processor based on the program trace signal of the at least one purported control processor.
Legal claims defining the scope of protection, as filed with the USPTO.
8. The system of claim 7, wherein the at least one monitoring processor being operable to classify each device processor of the plurality of device processors as being one of processing the message or not processing the message based on the respective program trace signal comprises the at least one monitoring processor being operable to classify each device processor of the plurality of device processors as being one of executing the command or not executing the command based on the respective program trace signal.
19. The method of claim 18, wherein operating the at least one monitoring processor to classify each device processor of the plurality of device processors as being one of processing the message or not processing the message based on the respective program trace signal comprises operating the at least one monitoring processor to classify each device processor of the plurality of device processors as being one of executing the command or not executing the command based on the respective program trace signal.
